Preinstalled software: Android 7

I'd like to use this device as daily driver. So I bought it used, then followed instructions on wiki. I built it using pmbootstrap, mostly to have FDE, then I booted plasma-mobile but sim detection didn't worked, then reflashed these time using prebuilt plasma. Secondly Tried prebuilt phosh and then discovered this Tried to communicate with modem with given command and result above.

I'm not sure what modem this device have (old or new qrtr), I've also tried to search any information about similar bugs but I was unable to find anything helpful.

Do you think it'd be good to extend bq-paellas Modem section?
